This study is aimed to provide a clinical and radiographic evaluation of 120 suitable subjects who underwent a total hip arthroplasty with MINIMA stem coupled with Delta TT or Delta ST-C cup.
This is a post-market, interventional, prospective, randomized, not comparative, open label study designed to reflect real life clinical practice as closely as possible.
641 studies on the registry are indexed under Osteoarthritis, Hip; 120 are open to participants now.
This study's enrollment of 120 is above the median of 90 across 457 interventional studies indexed under Osteoarthritis, Hip.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Minima Stem with ST-c Cup
Device: TT cup and ST-C cup
Minima Stem with TT Cup
Device: TT cup and ST-C cup
Patients are allocated in 2 different group (one with ST-C Cup and another one with TT Cup)
Harris Hip Score (HHS)
Functional changes in Harris Hip Score (HHS) from preoperative (baseline) to 3 years after surgery. The Harris Hip Score is composed of ten items covering foru domains: pain, fuction, absence of deformity and range of motion. The maximum score is 100 points. Pain domain contributes 44 points, function 47, Range of Motion 5 and absence of deformity 4 points. Results can be interpreted as follows: less than 60 points corresponds to a failed result, from 60 to 69 to a poor result, from 70 to 79 points to a fair outcome, from 80 to 90 to a good result ad from 90 to 100 to an excellent outcome. Overall, the outcome is considered satisfactory for values over 80 points.
Time frame: Pre-operative, 3 months, 6 months, 1 year and 3 years
Harris Hip Score (HHS)
Functional changes in Harris Hip Score (HHS) from preoperative (baseline) to 5 years after surgery. The Harris Hip Score is composed of ten items covering foru domains: pain, fuction, absence of deformity and range of motion. The maximum score is 100 points. Pain domain contributes 44 points, function 47, Range of Motion 5 and absence of deformity 4 points. Results can be interpreted as follows: less than 60 points corresponds to a failed result, from 60 to 69 to a poor result, from 70 to 79 points to a fair outcome, from 80 to 90 to a good result ad from 90 to 100 to an excellent outcome. Overall, the outcome is considered satisfactory for values over 80 points.
Time frame: 5 years
Implant stability
Radiographic implant evaluation and stability assessment at 6 months, 1 year, 3 years, 5 years after surgery
Time frame: 6 months, 1 year, 3 years, 5 years after surgery
Oxford Hip Score (OHS)
Functional changes in Oxford Hip Score (OHS) from preoperative (baseline) to 5 years after surgery. The Oxford Hip Score is composed of two domains (pain and function) with six items or questions in each that are scored as follows: each question can be scored from 0 to 4, with 4 being the best outcome, producing overall scores running from 0 to 48, with 48 being the best outcome. The calculation of the total score is based on the above-mentioned scoring system, with a score reported as excellent for more than 41 points, good from 34 to 41, fair from 27 to 33 and poor for less than 27 points.
Time frame: Pre-operative, 3 months, 6 months, 1 year, 3 years, and 5 years
Forgotten Joint Score (FJS)
Changes in Forgotten Joint Score (FJS) from 3 months (baseline) to 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after surgery. The Forgotten Joint Score is a 12 item questionnaire that integrates variables such as pain, stiffness, function on activities of daily living, ptients' expectations and activity levels and finally psychosocial factors. It consist of 12 questions scored using a 5-point Likert response format (never-almost never-seldom-sometimes-mostly) with raw scores transformed onto a 0-100 point scale. High scores indicate good outcome, that is, a high degree of "forgetting" the joint.
Time frame: 3 months (baseline) to 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after surgery
Survival Rate
Survival rate expressed with Kaplan-Meier estimator at 5 years after surgery
Time frame: 5 years
Safety assessment
Incidence, type, and severity of all the Adverse Events (AEs), Serious Adverse Events (SAEs), Adverse Device Effects (ADEs), and Serious Adverse Device Effects (SADEs) occurred at each follow-up.
Time frame: Intra operative, 3 months, 6 months, 1 year, 3 years, 5 years

Started Feb 2022 (actual). Primary completion is estimated for Feb 2027, 60 months after the start.
Of 226 interventional studies with no phase under Osteoarthritis, Hip, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 51. This study's planned 60 months is above that.
